Display During Automatic Watering

(Fig. Display during automatic watering)

Example:

• It is Friday (Fr) 18:45, the water computer is programmed for watering every 2 days (2nd).
• On/Off-Prog. is set to On (watering desired).
• The remaining watering time (RUNTIME) is 50 minutes.
• The dots between the hours and minutes are flashing. – The clock is running.
• The RUN TIME is counting down.

After the RUN TIME has finished the display shows normal operation.
If the valve is opened by a program it can be closed prematurely at any time by pressing the On/Off key 1 without influencing the program data (starting time, watering time and watering days).

Read/Change Program

You can run through the program levels to check the data you have entered by repeatedly pressing the Menu key and select and check the program steps by pressing O.K.
You can change the watering programs as described under "Programming".

Manual Program-Independent man On/Off Operation

After you have entered data, you can operate your water computer manually at any time, independent of the programmed watering times, by pressing the man On/Off key .
Press the man On/Off key once to open the water flow. Press the same key again to close the valve.
If you do not manually close the valve, for safety reasons, watering is ended automatically after 30 minutes. The remaining watering time (RUN TIME) is shown on the LCD display.

If the valve is opened manually and the manual watering time and a programmed watering time overlap, the programmed watering is suppressed.

Battery

Status Indicator

If the battery voltage falls below a certain level the Batt. indicator appears . It is possible to initiate watering manually even if the battery capacity is too low (valve no longer opens), but programmed watering times, however, are not initiated. Even if the battery capacity is too low to run a program, if the valve is open it will be closed.

The battery voltage is tested during the opening pulse. In this way you can test the capability of the battery at any time. To do this, simply press the man On/Off key . If the valve opens and the Batt. indicator does not appear then the battery does not have to be changed.

Changing the Battery

If you exchange the battery within 100 seconds, the data you have entered will be saved (program saved). When the battery is removed the LCD display extinguishes and programs will not run while the battery is being changed. When you have inserted a new battery, we recommend that you check the data as described under "Read/Change Program".

If you do not insert a new battery within 100 seconds, or if the battery power was already so low that the valve no longer opened, the water computer is RESET (all program data is deleted).You must re-program your water computer. The current date / time which was previously displayed remain unchanged within the given time.

Notes on Safety and Operation

For safety reasons only a 9 V alkali-manganese battery (alkaline) type IEC 6LR61 must be used.

• The minimum water output to ensure that the Water Computer functions correctly is 20-30 l/h. For example, at least 10 x 2-litre Drip Heads are required to control the Micro-Drip-System.
• The battery must be exchanged in time to prevent the Water Computer failing due to a low battery when you are away for longer periods of time. Make sure that the time the battery has been in operation and the time you are planning to be away does not add up to more than a year.
• The functional safety of the Water Computer depends on the capability of the battery. The Water Computer will only run for approx. a year if the alkali-manganese battery has a nominal voltage of at least 9 V. Check the battery before you buy it.
• To prevent water penetrating the battery compartment, the Water Computer may only be installed in a perpendicular position with the sleeve nut pointing upwards.
• Program the Water Computer with the tap turned off. In this way you can avoid getting wet when trying out the "man On/Off" function. You can remove the control unit from the housing to program the Water Computer.
• The control unit must be attached to the Water Computer during operation.
• Only use the Water Computer outdoors.
  
  The Water Computer must not be used indoors.
• The Water Computer must be stored in a dry place away from frost before the frosty season begins.
• The cover provided for the operating display must be used as shown in Fig. B.To protect the operating display against the weather the cover must be flipped over when you have finished programming the computer (Fig. B).
  Stick the programming help provided on the inside of the display cover.
• At high temperatures (over 60°C at the display) the LCD display may extinguish. This does not affect the program in any way.
  When the computer cools down the LCD display illuminates again.
• The max. temperature for the water flow is 40°C.
• The minimum operating pressure is 0,5 bar, the maximum operating pressure is 12 bar.
• Check the filter in the sleeve nut C regularly and clean if necessary.
• Avoid tensile strain. Do not pull the hose connected to the Water Computer.
• Only use clear fresh water.

Options

Anti-Theft Protection

To protect your Water Computer against theft, the GARDENA anti-theft protection (1815-00.791.00) is available at GARDENA Service. The bracket on the anti-theft protection is fitted onto the back of the unit. Note that the screw included cannot be loosened once it has been screwed in. The bracket can be used, for example, to attach a chain.
See (Fig. D)

GARDENA Soil Moisture Sensor

Together with the GARDENA Soil Moisture Sensor (Art. No. 1188) watering is controlled considering the soil moisture.
See (Fig. E)

Assembly

The Soil Moisture Sensor is connected to the socket on the back of the control unit
See (Fig. A).

How it Works

If the connected Soil Moisture Sensor indicates there is sufficient moisture then the watering program is either interrupted or not initiated.
Note: Manual watering (man On/Off) is still possible.

GARDENA Rain Sensor

Together with the GARDENA Rain Sensor (Art. No. 1189) watering is controlled considering natural precipitation.
See (Fig. F).

Assembly

The Rain Sensor, as an alternative to the Soil Moisture Sensor, can be connected to the connection socket 0 on the back of the control unit See (Fig. A).

How it Works

If the rain sensor indicates an adequate amount of rain, then the watering program is interrupted or not initiated.
Note: Manual watering (man On/Off) is still possible.

GARDENA Automatic Water Distributor

Connecting the GARDENA Automatic Water Distributor (Art. No. 1198) allows you to control up to 6 watering lines with your Water Computer Plus C 1030.
See (Fig. G).
Each output can be watered every 2nd day. Therefore, 3 outputs can be watered every day every 8 hours.
This is ideal where there is an insufficient amount of water or where individual areas of the garden have varying water requirements. It allows all watering lines to be operated one after another.
